Okay, so, didn’t consider marshadow was Ghost, and False Swipe was normal.... Good thing that Rockruff has Odor Sleuth. I’ll try it with Odor Sleuth and False Swipe! Because Odor Sleuth makes it ignore any non effectiveness defensively and offensively of Ghost types. So it’ll make False Swipe work.
